Abstract

The invention discloses an aluminum alloy gravity casting die with a good cooling effect, and relates to the technical field of gravity casting. The problem of cooling efficiency is solved. The aluminum alloy gravity casting die specifically comprises a base and a supporting seat, an upper and lower die assembly is arranged at the top of the supporting seat, an auxiliary assembly is arranged at the top of the base, the upper and lower die assembly comprises an upper die and a lower die, and a plurality of first U-shaped pipe combination pipes and a plurality of second U-shaped pipe combination pipes are connected to the inner walls of the other three sides of the non-opening side of the upper die and the inner walls of the other three sides of the non-opening side of the lower die in an embedded mode respectively. A pump located in a cooling water barrel is started, cooling water circulates through the first U-shaped pipe combination pipes and the second U-shaped pipe combination pipes, the upper die and the lower die are cooled in a heat transfer mode, and therefore the cooling speed of a casting is increased, the first U-shaped pipe combination pipes and the second U-shaped pipe combination pipes occupy the inner walls of the three sides of the upper die and the lower die, three sides are simultaneously cooled, so that the cooling efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of gravity casting, in particular to an aluminum alloy gravity casting mold with good cooling effect. Background technique [0002] Gravity casting refers to the process of injecting molten metal into the mold under the gravity of the earth, also known as gravity casting. The generalized gravity casting includes sand casting, metal casting, investment casting, lost foam casting, mud casting, etc.; Gravity casting mainly refers to metal mold casting. In gravity casting, different from other castings, gravity casting uses casting metal liquid, while other casting methods use pouring metal liquid. When casting, the liquid inlet pressure is small and the speed is slow. Want to improve The overall casting efficiency can only be controlled by subsequent cooling or demoulding steps. [0003] After retrieval, the Chinese Patent Publication No. is CN102029383B, which discloses a gravity casting mold for aluminum all...
